Jemalloc un-abandoned by Meta

4 hours ago

Meta emphasizes the long-term benefits of jemalloc, a high-performance memory allocator, in its infrastructure.
Meta is renewing focus on jemalloc to reduce maintenance, modernize the codebase, and adapt to new hardware and workloads.
Meta commits to open-source collaboration for jemalloc's development, welcoming community contributions.
Foundational software like jemalloc requires high rigor and adherence to core engineering principles.
Recent deviations from core principles led to technical debt, slowing progress.
Meta has engaged with the community, including jemalloc's founder, to reflect and change its approach.
The original jemalloc repository has been unarchived, with Meta continuing as stewards.
Key focus areas include technical debt reduction, huge-page allocator improvements, memory efficiency, and AArch64 optimizations.
Meta invites community feedback and collaboration to shape jemalloc's future.
